Agents for the treatment of airway disorders

ABSTRACT

The invention relates to the use of reversible proton pump inhibitors in the treatment of airway disorders.

TECHNICAL FIELD

The invention relates to the use of compounds from the class consisting of the acid secretion inhibitors for the treatment of airway disorders.

PRIOR ART

A whole series of compounds are known from the prior art which inhibit gastric acid secretion by reversible blockade of the proton pump and which have therefore also been designated as “reversible proton pump inhibitors” (RPPI) or recently as “APAs” (acid pump antagonists). These compounds should be suitable for the treatment of gastric and intestinal disorders.

DESCRIPTION OF THE INVENTION

Surprisingly, it has now been found that the reversible proton pump inhibitors, whose original field of use is the treatment of gastric and intestinal disorders, are particularly suitable for the treatment of airway disorders.

The invention thus relates in a first aspect to the use of reversible proton pump inhibitors in the treatment of airway disorders including bronchoconstriction.

Reversible proton pump inhibitors are designated as those substances which inhibit gastric acid secretion by blockade of the proton pump, but which, in contrast to the PPIs, do not bind covalently to the H⁺/K⁺-ATPase, the enzyme responsible for gastric acid secretion. The term “reversible proton pump inhibitor” according to the invention comprises not only the active compounds as such, but also their pharmacologically tolerable salts and solvates (in particular hydrates) etc.

Reversible proton pump inhibitors are described and claimed, for example, in the following patent applications and patents: EP 33094, EP 204285, EP 228006, EP 233760, EP 259174, EP 266326, EP 266890, EP 270091, EP 307078, EP 308917, EP 330485, U.S. Pat.

Commercial Utility

According to the invention, the reversible proton pump inhibitors are employed for the treatment of airway disorders in the form of ready-to-use medicaments. These medicaments are prepared by methods known per se familiar to the person skilled in the art. As medicaments, the reversible proton pump inhibitors are either used here as such, or preferably in combination with suitable pharmaceutical excipients or vehicles in the form of tablets, coated tablets, capsules, suppositories, patches (e.g. as TTS), emulsions, suspensions or solutions, the active compound content advantageously being between 0.1 and 95% and it being possible by means of the appropriate choice of the excipients and vehicles to achieve a pharmaceutical administration form exactly adapted to the active compound and/or to the desired onset of action and/or to the duration of action (e.g. a sustained release form or an enteric form).

The person skilled in the art is familiar on the basis of his/her expert knowledge with which excipients or vehicles are suitable for the desired pharmaceutical formulations. Besides solvents, gel-forming agents, suppository bases, tablet excipients and other active compound carriers, it is possible to use, for example, antioxidants, dispersants, emulsifiers, antifoams, taste corrigents, preservatives, solubilizers, colorants or, in particular, permeation promoters and complexing agents (e.g. cyclodextrins).

The active compounds can be administered orally, parenterally or percutaneously.

In general, it has proved advantageous in human medicine to administer the reversible proton pump inhibitor in a daily dose of, in particular, 0.1 to 1.5 mg/kg of body weight, if appropriate in the form of a number of, preferably 1 to 2, individual doses to achieve the desired result. In the case of a parenteral treatment, similar or (in particular in the case of the intravenous administration of the active compounds) as a rule lower dosages can be used. The determination of the optimal dosage and manner of administration of the active compounds necessary in each case can be easily carried out by any person skilled in the art on the basis of his/her expert knowledge.

The invention further relates to a pharmaceutical preparation for the treatment of airway disorders, which in an individual dose (tablet, capsule, etc.) contains a reversible proton pump inhibitor as active compound in a dose of between 3 and 40, in particular 5 and 20, mg.

If the reversible proton pump inhibitors are to be employed for the treatment of airway disorders, the pharmaceutical preparations can also contain one or more pharmacologically active constituents of other pharmaceutical groups. Examples which may be mentioned are: tranquillizers (for example from the group consisting of the benzodiazepines, e.g. diazepam), spasmolytics (e.g. bietamiverine or camylofine), anticholinergics (e.g. oxyphencyclimine or phencarbamide), local anaesthetics (e.g. tetracaine or procaine), and optionally also enzymes, vitamins or amino acids.

In particular to be emphasized in this connection is the combination of the reversible proton pump inhibitors with other pharmaceuticals which are customarily employed for the treatment of airway disorders.
